Comment additionner des forces ?
Quand une force A et une force B agissent sur un objet dans le même sens (vecteurs colinéaires), la force résultante (C) est égale à A + B, dans la direction de A et B.
Si la force A a plus d'intensité que la force B, la résultante sera plus proche du point d'application de A que du point d'application de B.Quels sont les 4 types de force ?
L'Univers est gouverné par quatre forces fondamentales : la force forte, la force faible, la force électromagnétique et la force gravitationnelle.
Leurs portées ainsi que leurs intensités sont différentes.Comment calculer la résultante de 3 forces ?
Si le corps est à l'équilibre, — les trois forces F1, F2 et F3 se trouvent dans un même plan (elles sont coplanaires) — les lignes d'action (droites qui portent les vecteurs force) passent par un même point (les forces sont concourantes) — la résultante ΣF = F1 + F2 + F3, c'est-à-dire la somme des trois forces, est
- La somme des forces extérieures appliquées à un système est reliée à son mouvement.
Si la somme des forces est nulle, le système est en inertie.
Si la somme des forces n'est pas nulle, la somme est reliée à la variation du vecteur vitesse du système par une approche de la 2e loi de Newton.

Introduction
In Unit 2 we studied the use of Newton's second law and free-body diagrams to determine the net force and acceleration of objects. In that unit, the forces acting upon objects were always directed in one dimension. There may have been both horizontal and vertical forces acting upon objects; yet there were never individual forces that were directed ...
Summary
A force board (or force table) is a common physics lab apparatus that has three (or more) chains or cables attached to a center ring. The chains or cables exert forces upon the center ring in three different directions. Typically the experimenter adjusts the direction of the three forces, makes measurements of the amount of force in each direction,...
Example
Suppose that a force board or a force table is used such that there are three forces acting upon an object. (The object is the ring in the center of the force board or force table.) In this situation, two of the forces are acting in two-dimensions. A top view of these three forces could be represented by the following diagram. A pack of five Artic ...
Goals
The goal of a force analysis is to determine the net force and the corresponding acceleration. The net force is the vector sum of all the forces. That is, the net force is the resultant of all the forces; it is the result of adding all the forces together as vectors. For the situation of the three forces on the force board, the net force is the sum...
Purpose
The purpose of adding force vectors is to determine the net force acting upon an object. In the above case, the net force (vector sum of all the forces) is 0 Newton. This would be expected for the situation since the object (the ring in the center of the force table) is at rest and staying at rest. We would say that the object is at equilibrium. An...

How many forces are acting on an object in a force board?
Suppose that a force board or a force table is used such that there are three forces acting upon an object. (The object is the ring in the center of the force board or force table.) In this situation, two of the forces are acting in two-dimensions. A top view of these three forces could be represented by the following diagram.
